Computer networking is an attempt to end the ''tyranny of geography". The goal is to make all data available to any system connected anywhere in the network. In a more compact form, it is known as "resource sharing". The remote compilers' concept permits a software package to be shared on the network using client-server and peer-to-peer networks. This setup allows the users to compile the source f...

Playing computer games is a popular recreational activity for young people. Creating a state-of-the-art commercial computer game is an incredibly difficult task. Writing a game like Pac-Man from scratch in a modern programming language is still difficult. Fortunately, several currently available tools make game creation easier. These tools can be used to create more complex games, but they offer o...

Real-time imaging systems are a special class that underlies important application domains that include industrial, medical and military. The main characteristic of a real-time imaging system is the need for deadline satisfaction. Admittedly, this definition is very broad and vague. The case can be made that every system is real-time. In a "hard" real-time imaging system even one missed deadline c...

Metamaterials are new artificial materials with unusual electromagnetic properties that are not found in naturally occurring materials. All "natural" materials such as glass, diamond and such have positive electrical permittivity, magnetic permeability and an index of refraction. In these new artificially fabricated materials - termed as negative index materials (NIM) or double negative (ONG) medi...

Bluetooth is a standard for short range, low power, and low cost wireless communication that uses radio technology. Over 2100 companies around the world already support Bluetooth technology. The wireless personal area network (WPAN) technology, based on the Bluetooth specification, is now an IEEE standard under the denomination of 802.15 WPANs. This work presents an overview about the Bluetooth co...

Refurbishing Michelangelo's David has produced several useful restoration guidelines. These guidelines can help restorers select the proper procedures for the task and, objectively, assess the results. The work also has helped us develop innovative ways to process and visualize 3D data in cultural heritage projects. The David restoration was an ideal test bed. We try various methodologies to suppo...

A Bluetooth scatternet is an ad-hoc network consisting of two or more Bluetooth piconets that are interconnected using bridge nodes. This interconnection allows devices that are not directly connected, and which may not be within transmission range of each other, to communicate. The scatternet formation has not been formally defined in the Bluetooth special interest group (SIG) specifications. As ...

Demands for network bandwidth increase daily. In order to meet our ever-increasing network bandwidth needs, one solution is to design and build the next generation Internet with an optical core infrastructure, with last connection provisioning time and unprecedented high data rates of 100 terabits per second and higher. An optical network is built by interconnecting various optical switches with w...
